@ zig321 – no need to worry about the status of dependents. The online status shows something similar for all of us. If the visa office needs any specific additional or missing info for a dependent, they will let you know accordingly.
@ NiqNok13 – yes, it usually takes 4-6 months from MR to receive PPR. I think this is most likely the case if the visa office has asked for some additional documents (like updated police clearance/forms etc) which will need to be evaluated. I think background checks to be done by the visa office based on the police clearance submitted take the most time especially for persons who have lived in several countries or travel frequently or originally belong to certain countries. Some people have got PPR in shorter time which could be due to plain and simple luck or the background checks were done faster or earlier. I guess you still have to wait a couple more months to hear back from ADVO. The medical test results are valid for 12 months and the VO tries to process the case within this period otherwise they will have to ask for fresh medical tests. the good thing is you've had your medical as some applicants on this forum have been waiting for MR for quite sometime for reasons unknown.
